Background: Bariatric procedures are effective options for weight loss (WL) in the morbidly obese. However, some patients fail to lose any after bariatric surgery, and mid-term maintenance is variable. The aim of this study was investigate whether initial WL could predict maintenance. Methods: Eighty were enrolled, whom 44 treated with BioEnterics Intragastric Balloon (BIB), 21 laparoscopic adjustable gastric lap-banding (LAGB), 15 sleeve gastrectomy (LSG). Percentage body percentage excess...

To analyze early remission, complications, and pituitary function recovery after pure endoscopic endonasal transsphenoidal surgery (PEETS), a novel method in adenoma treatment.Testing of all basal hormone values magnetic resonance imaging (MRI) were performed preoperatively postoperatively (postoperative MRI only nonfunctioning adenomas) 117 consecutive patients who underwent PEETS the period between 2007 2010. The series consisted 21 somatotroph adenomas, 61 prolactinomas, 4 corticotroph 31...

Intrathyroidal parathyroid carcinoma is extremely rare clinical entity with potentially multiple diagnostic pitfalls. We report a case of 40-year-old man presented classical manifestations primary hyperparathyroidism, severe hypercalcemia and profoundly increased serum hormone level. Neck ultrasonography demonstrated multinodular goiter predominant 34 mm nodule in left thyroid lobe. Additional 16 was found beneath the Routine percutaneous fine-needle aspiration indicated follicular...

Although various metabolic hormones have been implicated in bariatric-related weight loss, their use as predictors of loss is unknown. Our study evaluates changes after bariatric surgery, and role loss.This nonrandomized included 51 patients, 21 underwent laporascopic adjustable gastric banding (LAGB), 15 laparoscopic sleeve gastrectomy (LSG) Roux-en Y bypass (RYGB). Serum ghrelin, leptin, insulin, growth hormone, HOMA-IR HOMA-β was recorded at baseline 1, 3, 6 12 months, correlated with...

Abstract Background The purpose of this study was to detect parameters that could serve as predictors radioactive iodine (I‐131) ablation failure in patients with low‐risk and intermediate‐risk differentiated thyroid carcinoma (DTC). Methods Our cohort included 740 DTC who received postoperative I‐131 remnant ablation. Anthropometric, biochemical, pathohistological were analyzed correlated outcome using multivariable logistic regression models. Results Treatment rates higher <53 years,...

Introduction and aims: The most recent hypothesis postulated that early restoration of euthyroid state in patients with Graves’ disease changes the course leads to better control. Therefore, we analyzed efficacy methimazole therapy restored euthyroidism active on first control visit. Patients methods: We included 63 total T4 level >190 nmol/L or T3 >7 diffuse goiter no previous episodes hyperthyroidism. All received initially high doses (60–80 mg) followed by a rapid dose reduction. Results:...

We report a case of 49-year-old woman with biopsy-proven multisystemic Langerhans cell histiocytosis (LCH) hypothalamic involvement documented on F-FDG PET/CT. Chemotherapy combination vinblastine, prednisolone, methotrexate, and 6-mercaptopurine was carried out. Two months later, 90% reduction the tumor mass noted magnetic resonance imaging, but no signs pathological accumulation. The patient died 4 we found LCH autopsy. Our highlights need for further studies regarding role PET/CT in...

Abstract Diet rich in lipids and hyperlipidaemia increases incidence of atrial premature beats all supraventricular arrhythmias. The aim the study was to investigate prevalence patients with AV re-entry tachycardia (AVRT) nodal (AVNRT). We conducted a retrospective, cross-sectional, case-control that included consecutive for whom AVRT or AVNRT confirmed during electrophysiology study. Age gender-matched admitted hospital outpatient clinic various reasons were randomly served as control...

Aims: To investigate the effectiveness of cardiogoniometry, a novel, non-invasive method, in diagnosing coronary artery disease (CAD) women and compare it with exercise-ECG test, by using angiography as reference method. Methods: It was single-centre, case-series study including consecutive female patients stable angina pectoris (AP) undergoing angiography. Exercise-ECG done according to Bruce protocol, cardiogoniometry were obtained prior Clinically significant CAD has been defined one or...

Purpose . In low-income countries, prolactinomas are difficult to manage with dopamine agonists (DA). We compared the effectiveness of DA in microprolactinomas as a first line treatment and adjuvant therapy for residual macroprolactinomas treated surgically. Methods Our retrospective study analyzed 78 patients, 38 40 macroprolactinomas. Microprolactinomas were DA. Macroprolactinomas microsurgical or endoscopic adenomectomies Surgical remission was defined normoprolactinemia three months...
